The simultaneous addition of epinephrine and salmon glucagon to catfish (Ictalurus melas) and trout (Salmo gairdneri) hepatocytes did not induce greater increases in glycogen phosphorylase a activity and in glucose release than those caused by epinephrine alone. The effects of epinephrine are greater than those of glucagon. Propranolol added to the hormonal pool blocked the epinephrine effects. In trout cells, epinephrine and glucagon-like peptide (GLP) had similar effects and when they were added simultaneously the stimulation of metabolic indices was higher compared to that obtained with either epinephrine or GLP. However, the effects were not additive. In the presence of epinephrine plus GLP the inhibitory effect of propranolol was not evident, due to the effect induced by GLP, on which propranolol was not effective. This may indicate that epinephrine masks the GLP effect. Results could mean that epinephrine and glucagon-family peptides act in catfish and trout hepatocytes through different receptors on the same pathway leading to glycogen phosphorylase a activation.
